There is a certain feedback expected, mostly from the peers. A teacher must realise that by these activities students learn new things and that is why they should not make comments that might cause a loss of motivation. Possibilities of assessment vary from activity to activity. The output of activity 2 is a work text created by a group of pupils and further used in activities 5 “Scientific conference” and 6 “Interview”. Following the activities it is possible to discuss whether the produced work texts contained all the important information, what their quality was and what they lacked.
In activities 4 and 7–10 the concern is to understand relations and to apply the knowledge. The topic should be concluded by reflexion (activity 11, 12) based on which a teacher can assess how students incorporate new information into their own ideas.
The teacher can assess whether students
– adequately interpret notions, such as blood cell, blood type, antigen, antibody and other;
– can explain what happens after incorrect transfusion;
– can determine child’s possible blood types based on blood types of parents;
– can speak about a protective role of white blood cells and antibodies in plasma;
– are familiar with the ways blood transfers substances from the environment to cells and the other way around.
